Damn this is hard for a beginner like me lol. Anyways let me try to clear this up.
I want to use the fan of knives model. I want the ability to to do an initial damage to the targets that the knives hit, then poison the targets, slowing them by a certain percentage and also doing damage over time.
Here's what i've gotten so far. I tried using shadow strike as a template instead. The problem is that it makes me target a unit instead of releasing the knives and hurting the enemies around the hero with just a click. Also the shadow strike ability doesn't have the Multiple Targets option under the abilities. So how would I do all this? I don't necessarily want it done for me but I want to be guided on how to do it so that I can learn.
PS: I did find the unit in range trigger but I think I am doing it wrong.
